i got this error when trying to install

I am trying to use this to decrypt a dash media segment from a vod movie

i am using nodejs 18 this is the code i am using

`
keys = {
[row.vkid]:row.vkey
};

     const encrypted = fs.readFileSync(combinedLocation);

    mp4decrypt.decrypt(encrypted, keys).then(decrypted => {
         fs.writeFileSync('dec.mp4', decrypted)
    })

`

the media file does not play after decryption using vlc i get the following errors

I have tested the exact same media files kid and key using mp4decrypt running it as an spawned process and the output plays correctly it is only when using this modual i run into issues but there are no error messages or anything provided for failed decryption or anything so its really hard to tell what the issue is

Hi

Is there scope for adding additional bento4 utilities to this package? namely mp4split and mp4pssh

Hi could this be updated to use the latest bento4 ?

i have tried using it but i get the following errors

WARNING: atom serialized to fewer bytes than declared size
WARNING: padding would be too large

i have checked using mp4 decrypt its self and it works so i assume its because this is using an older version
